Study of physico-chemical properties of diatomiteAlgeria: Application to the thermal insulation ofliquid steel bath

Abstract: The purpose of this paper is tocharacterize and to evaluate the diatomitepowder of Sig region (West Algeria) withoutfluorine by powder generally used in tundish

The purpose of this paper is to testand to evaluate the diatomite of Sig region (West Algeria) to substitute the main mould powder used incontinuous casting of steel for

The purpose of this paper is to test and to evaluate the diatomite of Sig region (West Algeria) to substitute the main mould powder used in continuous casting of steel for

The elaboration of our films has been carried out using thermal evaporation process (physical vapor deposition) under 1 × 10 -6 mbar vacuum from an electrically heated tungsten boat,

These unicellular algae are surrounded by a "shell" in silica, frustule, the accumulation of the substance can lead to the formation of a rock.In this work we determine

In this work we have focused our attention to evaluate covering powders for continuous casting steel.The aim is utilization of Algerian diatomite as a covering powder in the tundish;

Through the identification of thermal proprieties by many thermal analysis methods, we have obtained high insulting properties in high temperature up than 1400°C when the beginning
